Chapter 9 Replacement Procedures

Replacing an I/O Module

Step 13

Grasp the front of the module with one hand and place your other hand under the module to support its
weight.

Step 14

Align the module to the open supervisor slot in the chassis and push the module into the slot until it
makes contact with the midplane.

Step 15

Simultaneously push both ejector levers inward until they come in contact with the face of the module.

Step 16

The module should be fully seated in the slot and the captive screws should be aligned with their holes
in the chassis. The EMI gasket should close the gap between this module and the next module.

Step 17

Screw in the two captive screws to the chassis and tighten them to 8 in-lb (0.9 N·m).

Step 18

Reconnect the console cable to the CONSOLE SERIAL PORT as explained in the

“Connecting to the

Console” section on page 6-2

Step 19

If the previous supervisor module was connected to an asynchronous device through a modem, connect
the modem cable to the COM1/AUX SERIAL PORT as explained in the

“Connecting to the Console”

section on page 6-2

Step 20

Reconnect the network management cable to the MGMT ETH port as explained in the

“Setting Up the

Management Interface” section on page 6-4

Step 21

Reconnect the CMP cable to the CMP MGMT ETH port as explained in the

“Connecting the Supervisor

CMP Port” section on page 6-5

Step 22

Verify that the module has 4 GB of memory by using the

system switchover

command to make the

downgraded module active and using the

show system resources

command.

Step 23

If you need to downgrade the other supervisor module to 4 GB (both modules must have the same amount
of memory), repeat Steps 2 through 21.

Step 24

Verify that the downgraded module has 4 GB of memory. If there are two supervisor modules installed
in the switch, use the

system switchover

command to make the downgraded module active, and then use

the

show system resources

command. If there is just one supervisor module installed in the switch, use

the

show system resources

command.

Step 25

If you need to downgrade another supervisor module to 4 GB (both supervisor modules in a switch with
two supervisors must have the same amount of memory), repeat Steps 2 through 24.

Replacing an I/O Module

The Cisco Nexus 7010 switch has up to eight I/O modules, and a Cisco Nexus 7018 has up to 16 I/O
modules. These modules are located on the front of the chassis. You can replace one of these modules at
a time while the switch is operating.

Note

If you are installing F2 I/O modules, all of the fabric modules in the switch must be Series 2 fabric
modules.
